BACKWATER AND ANIMAL GATE.

SPECIFICATION forming part of Letters Patent No. 364,206, dated June 7,1887.

Application filed March 25, 1887. Serial No. 232,395. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY H. BALTZLEY, a citizen of the United States,residing at Assumption, in the county of Christian and State ofIllinois, have invented certain new and useful Improvements in Backwaterand Animal Gates; and I do declare the'following to be a full, clear,and exact description of the invert tion, such as will enable othersskilled in the art towhich it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to traps or gates for drain-tiles of that classwhich are designed to be placed, preferably, at the end of the tile, forexcluding vermin, animals, backwater, &c., therefrom, and which willallow the water to pass out freely.

The object of the invention is the production of a simple and economicaldevice which can be placed on the market complete and can be readilyapplied by the purchaser without calling in skilled labor.

The improvement consists in a self-adjusting thimble or frame, which canbe quickly applied or inserted within a tile, and will expandsufficiently to hug the sides of the tile, so as not to be readilydislodged, and a gate hinged at its upper end to said frame and adaptedto close the tile against the entrance of foreign matter in onedirection, but will permit the drainings to pass out freely in theopposite direction. Said gate is concavo-convex and made of flexiblematerial, so it can be opened or closed more or less to adapt it totiles of different size.

The improvement further consists in the novel features of constructionhereinafter more fully set forth, claimed, and shown in the annexeddrawings, in which- Figure 1 is a perspective view, parts being brokenaway, of the frame and gate constructed in accordance with and embodyingmy invention; Fig. 2, an end view of a draintile provided with myimproved device.

The frame or thimble A. may be of any deeign matter. section andcomposed of flexible material, so

sired length, and is composed of sheet mateinto which it is designed tobe fitted, which in the presentinstanee is circular. The ends arenormally separated, as shown in Fig. 1, but are adapted to overlap whenthe device is in position, as shown by Fig. 2.

The gate or valve B is hinged atits upperend to the frame, and is ofsuch length that it illclines rearward, which will allow the water topass out, but will exclude the entrance of for- It is concavo-convex incross its edges can be separated or brought closer together forincreasing or diminishing the width and size of the gate to suitdifferent grades of tile.

Fig. 1 represents the device as placed on the market, and to adjust itall that is necessary is to compress the frame and push it in the end ofthe tile, when it will expand and hug the sides of the tile so noordinary pressure will accidentally force it out. Previous to theinsertion of the frame in the tile the gate is contracted or expanded,according as the bore of the tile may require, as will be readilyappreciated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. The herein shown and described device for the purposes set forth,composed of the self -adjusting or expansiblc frame and the gate orvalve hinged at its upper end thereto, substantially as specified.

2. The combination, with the sclfadjusting or expansible frame, of thegate concavoconvex in cross-section and composed of flexible material,whereby the sides or edges can be separated or brought closer togetherfor adapting the gate to different grades of tile, substantially as setforth.

In testimony whereof I affix my signaturein presence of two witnesses.

HENRY H. BALTZLEY.
